CHARACTERISTIC CALCULATION METHOD FOR SOLAR CELL AND PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a calculation method for reproducing highly precise solar cell characteristics, using data of short-circuit current, open voltage and a maximum power operating point of a solar cell with temperature and solar radiation intensity in a reference state.SOLUTION: Using data of short-circuit current, open voltage and a maximum power operating point of a solar cell with temperature and solar radiation intensity in a reference state, a parameter value for determining characteristics in a reference state is calculated. Next, temperature coefficients of open voltage and reverse saturation current are calculated using a calculated parameter, and short-circuit current, open voltage and a maximum power operating point at a predetermined temperature are calculated from the temperature coefficients.
